What is Uniswap v3 (Polygon)?

## What Is Uniswap (V3) Polygon? Uniswap is a [decentralized exchange](https://coinmarketcap.com/alexandria/glossary/decentralized-exchange-dex) (DEX) that introduced the [automated market maker](https://coinmarketcap.com/alexandria/glossary/automated-market-maker-amm) (AMM) model for the first time in the market. With this innovation, traders tap into a constant pool of liquidity and trade against an algorithm using a constant product formula. With its V3 version, the exchange branched out to blockchains other than [Ethereum](https://coinmarketcap.com/currencies/ethereum/) for the first time. After the introduction of the AMM model in V1, the V2 version allowed trading between different [ERC-20](https://coinmarketcap.com/alexandria/glossary/erc-20) token pairs instead of [swaps](https://coinmarketcap.com/alexandria/glossary/token-swap) between [ETH](https://coinmarketcap.com/currencies/ethereum/) and ERC-20 tokens. This reduced [slippage](https://coinmarketcap.com/alexandria/glossary/slippage) and introduced protocol fees to continue the exchange’s development. The V2 version also introduced [wrapped Ether](https://coinmarketcap.com/alexandria/article/what-is-wrapped-ethereum-weth) instead of native Ether as liquidity for token pairs. In the V3 version, [liquidity providers ](https://coinmarketcap.com/alexandria/glossary/liquidity-provider-tokens-lp-tokens)can build unique price curves and centralize their capital at desired prices to improve capital efficiency. It also activated automatic removal of capital if prices change significantly and exceed the LP’s price range. With the introduction of V3, Uniswap also launched on Polygon for the first time. Thanks to its lower gas fees, users can now access a much more affordable trading experience ## Who Is the Founder of Uniswap (V3) Polygon?
